Hi I see this: /lib/security/pam_unix.so /lib/security/pam_unix_acct.so /lib/security/pam_unix_auth.so /lib/security/pam_unix_passwd.so /lib/security/pam_unix_session.so lsmod | grep pam (nothing) I dont know how does it works... I have: apt-cache policy libpam-modules libpam-modules: Instalados: 0.79-4 Candidato: 0.79-4 Tabla de versión: *** 0.79-4 0 990 ftp://ftp.fr.debian.org testing/main Packages kernel: Linux 2.6.20-rc5-rt2 #2 SMP PREEMPT Mon Jan 15 22:24:12 EET 2007 i686 GNU/Linux But, non root users can't get realtime privileges. Lee told me to use something like this into /etc/security/limits.conf @audio hard rtprio 99 @audio hard nice -20 @audio soft nice -20 @audio hard memlock 500000 My user is into the audio group, of course But the problem is still here: no realtime JACK audio for non root users... I cant install an Ubuntu libpam-modules into this system, because it will break the package dependency system.
